TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO contact with acid(s) , alcohol , oxidants and water .
Dry sand, special powder. NO water. NO carbon dioxide, foam.
EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acid(s) , alcohol , oxidants and water .
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

•INHALATION
Local exhaust or breathing protection.
Fresh air, rest.
•SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
•EYES
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth.

PHYSICAL STATE; APPEARANCE:
SILVERY- WHITE TO GREY POWDER .

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
Reacts with water and alcohols , and violently with oxidants , strong acids , strong bases , and chlorinated hydrocarbons causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Al) 5 mg/m3 as TWA (pyroforic powder) (ACGIH 2000). TLV: 10 mg/m3 as TWA (metal dust) (ACGIH 2000).
MAK: 4 mg/m3 (Inhalable fraction), 1.5 mg/m3 (Respirable fraction);
Pregnancy risk group: D;
(DFG 2008).
OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation .

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by repeated or prolonged exposure to dust particles. The substance may have effects on the nervous system , resulting in impaired functions .
